Legislative efforts to repeal and replace the Affordable Care Act have failed. But President Trump promised in a Tweet this week to do what Congress couldn't, with, in his words, "the power of the pen." On The Sound of Ideas, we'll convene a panel of health care policy experts to discuss what Trump might do to alter Obamacare, and what the administration already has done. And we'll take your calls. Later, we'll meet NPR's Social Science Correspondent Shankar Vedantam. His "Hidden Brain" show debuts on WCPN tomorrow night at 9 and seeks to explain why we do what we do.

Guests:

-Loren Anthes, Public Policy Fellow, Medicaid Policy Center, The Center for Community Solutions
